This is a reconditioned 12 volt LiFEPO4 battery. These were warranty batteries that were returned due to a mis-configured BMS, and thus the Tesla cars they were designed for had almost immediate issues. Basically they were manufactured with a "normal" BMS, not the Tesla specific one required. Original capacity was 30 AH (5 hour test). We did a full test of 35 amp discharge from full to 10v and all are within 5ah of rated capacity. Some reduction in capacity would be expected due to the higher current test we performed.

There are different types available - there is the option of post or screw terminals and also regular or reverse terminals. If you have a preference, please put it in the order notes and we will do our best to accommodate your request. The majority of these batteries have terminals on the opposite side when compared to the Insight's original battery. Make sure to verify polarity prior to connecting the battery to the car.

These batteries come with a 30 day warranty only.
